of parts hereinafter shown, described, and

claimed.

Figure 1 is a front elevation of my improved device, parts thereof beingin section to more clearly. illustrate the same. Fig. 2 is a sideelevation of the device. Fig. 3 is a plan view thereof. Fig. 4 is anenlarged cross-sectional view taken approximately on the line 4 4 ofFig. 3. Fig. 5 is a horizontal sectional view taken approximately on theline 5 5 of Fig. 2. v

Referring by numerals to the accompanying drawings, 1 indicates asuitable base, to

, openings is a valvecomprising two end disks 7, intermediate of whichis the central disk 8,'said disks being connected'by the webs 9.Discharging. into'the centralone of the con1- partments withinthevalve-casing is a suitable connection 10, through which fiuid underpressure is discharged into said central chamber, and leading from thechambers immediately above and below said central chamher are suitabletubular connectionsll, the same leading to the valve or other mechanismthat is operated bymy improved device.

Leading from the top and bottom chambers within the valve-casing aresuitable tubu lar connections 12, that combine with or are connectedto awaste or discharge pipe 13. Formed integral with the left-hand side ofthe valve-casing 4 is a laterally-projecting arm I 14, through which isformed a screw-threaded aperture, in which operates theexteriorlyscrew-threaded lower end of a vertical post 15, the same beingprovided with an integral disk 16 adjacent its upper end. Seated in theupper end of this post is a pin 17, that forms a fulcrum for ahorizontally-arranged arm 18, one end of which projects to a pointdirectly over the center of the valve-casing 4, and a suitableconnection 19 is made from said end of the arm 18 to the upperend of thevalve that operates within said valve-casing. A stufi'ing-box 20 islocated in the top of said valve-casingaroundthis connection 19. Uponthe opposite end of this arm 18 is adj ustably located a weight 21,which counterbalances the weight of the valve within the'valve-casing 4,and passing through said arm at equal distances on each side from thefulcrum thereof are screw-threaded pins 2:2, with the lower ends ofwhich are formed integral the heads 23, into which screw thecontact-points 24, thatlie immediately over the face of the disk'16. Apair of. ears 25 are formed integral with the top of the arm 18immediately above the fulcrum thereof, and between said cars is fulcrumed' a horizo'ntallyarranged tube 26', the ends thereof being closed bythe caps 27 and 28 -and there being a ball 29 located within said tube.Formed integral with the cap 28 is a ring '30, through which ing-nuts 32are located upon said screwouter end of which carries a contact-point39, that is positioned immediately above the right-hand one of thecontact-points 37, and adj-ustably held immediately above the lefthandone of the contact-points 37 is acontactately above the arm 33 is ashort arm 38, the

point 40. An electrical conductor 41 leads from the arm 38 to one poleof a suitably-lo cated battery 42 and from thence to one of thebinding-posts of an alarm-bell 43, and another conductor 44: leads fromthe opposite binding-post on said bell to the end of the arm Leadingfrom the contact-point 40 to the conductor 41 is a short conductor45.Passing through the ring 35 on the end of the arm 33 is thescrew-threaded lower end of a vertically-moving rod 16, the same beingprovided with adjusting-nuts 47, one above and one below said ring 35.

Assumingthatthe parts are balanced or are in the positions shown in Fig.l and that the rod 31 is moved upwardly when the lower nut 32 upon saidrod strikes the ring 30, carried by the cap 28, said ring and cap,together with the end of the tube 26, on which said cap is located, willbe elevated and the ball 20 will roll to the opposite end of said tube.lVhen this movement takes place, the side of the tube into which theball has rolled will engage against the upper end of the left-hand oneof the adjusting-screws 22 and will depress the same, which will lookthe bar 18 upon the pivot-pin l7, throwing the weighted end downwardlyuntil the left-hand one of the contact-points 2i strikes against thedisk 16, and this movement necessarily raises the opposite end of saidbar 18 and elevates the valve within the valve-casing. As said valve isdrawn upwardly in said valve-casing communication will be establishedbetween the chambers into which the inlet pipe 10 leads and the chamberimmediately below said first-mentioned chamber and at the same timecommunication will be established be tween the chamber immediately abovethe chamber in which the inlet-pipe 10 leads and the top chamber or theone from which the discharge pipe 12 leads. Consequently if compressedair is passing through the valve said compressed air will enter the pipel0,to be discharged therefrom into the central one of the chambersbetween the partitions 5, and pass from thence downwardly into the nextadjacent chamber, from thence through the top one of the tubularconnections 11 and be delivered to a point where it is desired toutilize said compressed air, and simultaneous with this action theopposite pipe 11 becomes an exhaust-pipe and the back pressure throughsaid pipe discharges into the chamber above the central chamber, inwhich'the pipe 10 discharges, and from thence the compressed airdischarges into the top chamber and through the discharge or exhaustpipe 12. When the rod 31 moves downwardly, the nut 32 thereon willstrike against the upper side 01": the ring 30 and a reverse movement ofthe parts just described will take place and the valve will be lowered,so that the top disk 7 closes the opening through the top partition 5,the central disk 8 closes the opening in the partition immediately belowthe central chamber, into which the inlet-pipe 10 leads, andcommunication will be established between the two lowermost chambers andbetween the central chamber and the one immediately above it. Thedistance that the rod 31 has to move before the tube 26 is ac tuated isregulated by the adjusting-nuts 32 upon thescrew-threaded portion ofsaid rod. It is essential that the movement of the rod 46 besimultaneous with that of the rod 31. The adjusting-nuts 47, locatedupon the rod 46, are normally farther apart than are the adjusting-nuts32 upon the rod 31, said nuts being so located as that they will notengage the ring 35 on the end of the fulcrumed arm to sound the alarmuntil after the valveoperating mechanism has actuated. Thus the alarm issounded only at a time after the valve has been actuated, and the rod 31continues to move upwardly or downwardly, as the case may be, therebyendangering breakage of the various parts of the valve-actuatingmechanism. When the rod 46 continues in its upward movement, the lowerone of the nuts a? thereon will strike against the under side of thering 35, thus raising said ring and the end of the arm 33 upon whichsaid ring is located, and as said end of the arm moves upwardly theright-hand one of the contactpoints 37 will engage against thecontact-point 39, thereby closing the circuit through said arm 33, bar38, conductor 4.1, battery 42, bell 43, and conductor 44. When the rod4:6 descends past its normal lowered position, the upper one of the nuts47 will engage upon the top of the ring 35 and a contact will be madebetween the left-handone ofthe contact-points 37 and the contact-point4.0, thereby closing the circuit and sounding the bell 4E3. The operatoror attendant will immediately know that the rod 31 is not operatingproperly when the bell sounds.

A device of my improved construction is especially applicable for use inconnection with thermostats, which thermostats are used to elevate therods 31 and 46, and the compresed fluid that passes through the valvemay be led to and through the valve that is located in the pipe thatsupplies the hot air, water, or steam to the heating system in the building in which the valve-operating device and alarm are located.
